我们的工作平凡得被人看不起,但我们却很自豪,因为我们擦试着祖国的窗口,让国内外游客带走的,不仅仅是登上万里长城的骄傲,也带走对北京和中国优美环境的美好回忆。 ——赵国旺的话
We are proud of our work in an ordinary way, but we are very proud because we have scrubed the window of our motherland so that domestic and foreign tourists can take away not only the pride of the Great Wall and the beautiful scenery of Beijing and China Good memories of the environment.
